Answer:
The correct answer is D) 7+(3+1)=(7+3)+1
Step-by-step explanation:
The associative property of addition states that it doesn't matter how you group numbers inside of parenthesis, it gives you the same answer. So even though the groupings are different in that example, the answer is still the same.
6 decimeters is equal to 600 millimeters
Answer:
B
Step-by-step explanation:
I took the quiz
$715
3% of 550=16.5. 16.5*10=165. 550+165=715.
Let’s call the distance travelled on the first day ‘x’.
If the distance they drove on the second day was 5 times the first day, we can write it as ‘5x’.
And now, if we add the distance travelled on the first day and the second day, you’ll have the total distance travelled (which we know is 240 miles from the question).
Therefore:
x + 5x = 240
6x = 240
x = 240/6
x = 40
x (which is the distance travelled on the first day) is equal to 40, therefore your final answer is 40 miles.
